Environment? As in things placed in our food?
Environment? As in things placed in our food?
A lot of epigenetics takes place at the very beginning, in utero. And all exposure the mother got can play a part. Nearly every young woman has toxic BPA plastic in her (as yet unused) uterus these days. Among all kinds of other things, including what she eats and drinks, through her bloodstream, of course. Including even things that she breathes or that touch her body. The skin allows toxins into the bloodstream as well.
In my opinion we probably need to address this through science education. People blithely put on a dry cleaned shirt next to their skin. People eat brightly colored candy, sit in new cars (that smell = neurotoxins), eat pesticides in their veggies, sit for hours in a room filled with toxins (coming from the couch off gassing, the mostly plastic carpet, the cleaning sprays, the plug in neurotoxic scents, the water bottle, the lotion on the skin, the microwaved in plastic dinner...
What are we doing to ourselves? We need to address this.
In a minority of cases the environmental influences can turn the expression of genes on or off in either direction.
